OEM Carrier Single Run Capacitor 4 MFD 370V for Model PY2PEB060115AA

This is the genuine OEM Carrier single run capacitor for the PY2PEB060115AA packaged unit. The run capacitor remains in the circuit the entire time the fan motor or compressor is operating, providing continuous phase-shift current that keeps the motor running efficiently. When this capacitor fails, you'll typically notice symptoms such as a humming motor that won't spin up, warm air from the supply registers, or the unit shutting down shortly after starting. Replacing it with the correct OEM-spec part restores factory performance and protects downstream motor windings from stress.

• Specs: 4 MFD (microfarad) | 370 VAC | Oval case | ±5% factory tolerance | 50/60 Hz | Replaces OEM part numbers P291-0403, P291-1003, P291-2503 and legacy cross P/N 97F5704
• OEM vs Generic: This OEM Carrier/Totaline capacitor is manufactured to exact factory tolerances with high-grade metallized polypropylene film and a UL-approved pressure-sensitive interrupter — tested to 60,000 service hours. Generic aftermarket capacitors often run ±10% MFD deviation, which accelerates motor wear and can shorten compressor life.
• Install difficulty: 1/5 — One of the simplest HVAC repairs. Tools needed: 1/4" or 5/16" nut driver, needle-nose pliers, multimeter (to verify discharge). Always shut off power at the disconnect and allow 5 minutes for the capacitor to self-discharge before touching terminals. Photograph existing wiring before removal.
• Warranty: 1-year OEM factory warranty. Ships same business day from our warehouse when ordered before cutoff.

Compatibility: Engineered for Carrier model PY2PEB060115AA packaged units. Always verify the MFD rating and voltage on your unit's data plate before ordering — voltage ratings of 370V and 440V are not interchangeable downward. Have questions about fitment? Our HVAC parts specialists verify compatibility before you order — contact us before purchasing if unsure.
